2 inner grease seals, 1 ea side.
A little silicone keeps the grease from leaking out of the outer drive flanges & dust cap...
Thanks bud. I wasn"t sure if the silicone was enough. I hate to get into a repair to find I need more parts. I got the pads, rotors, hardware and lube only to find out there's more to doing the front brakes than the rears. The rear was a cake walk.
